Falling asleep: we all have to do it, but all too often it takes longer than we’d like. For an innovative solution to this problem experienced by many, hacker Youz has come up with the Fall Asleep Device, or FADing as it’s also known.

FADing takes the form of a nicely-cut piece of wood that emits an LED light, as well as another that shines via a piece of acrylic embedded toward the top of the device. The idea is that this light can be seen whether you fall asleep on your back or side.

In action, the unit’s light intensity varies several times per minute, prompting the user to breathe in when the intensity of light increases, and breathe out when it fades. It slowly decreases breath frequency from 11 to 6 breaths per minute, causing the user to fade into a relaxed state.

An Arduino Nano forms the brains of the gadget, and a pair of buttons on the bottom are used to power up and change settings. Cleverly, when being used it keeps itself on via a relay, meaning no power is used when FADing is in an off state.

Be sure to check it out being demonstrated in the video seen here!
